Yatin Tariyal conducted an experiment to determine Faraday's law of electromagnetic induction. The experiment involved winding a copper wire around an iron rod and placing a strong magnet near the rod. Yatin found that moving the magnet in and out of the rod induced a voltage in the copper wire due to changing magnetic flux. This verified Faraday's law, which states that a changing magnetic field induces an electromotive force in a nearby conductor. Yatin concluded that Faraday's law describes an important electromagnetic concept that underlies many technologies in modern life.

4|Page INTRODUCTION Faraday’s Law of Electromagnetic Induction
It is a basic law of electromagnetism predicting how a magnetic field
will interact with an electric circuit to produce an electromotive force (EMF). It is the fundamental operating principle of transformers, inductors and many types of electrical motors and generators. Faraday explained electromagnetic induction using the concept of lines of force. These equations for electromagnetic induction are extremely important since they provide a means to precisely describe how, many natural physical phenomena in our universe and behave.
The ability to quantitatively describe physical phenomena not only
allows us to gain a better understanding of our universe, but it also makes possible a host of technological innovations that define modern society. Understanding Faraday’s laws of electromagnetic induction can be beneficial since so many aspects of our daily life function because of the principles behind Faraday’s law. From natural phenomena, such as the light we receive from the sun, to technologies that improve our quality of life, such as electric power generation, Faraday’s law has a great impact on many aspects of our lives.
5|Page Magnetic Field Inside a Solenoid Electromagnetic Induction
Faraday’s law describes electromagnetic induction. Whereby an
electric field is induced, or generated by a changing magnetic field.
In Faraday’s first experimental demonstration of electromagnetic
induction, he wrapped two wires around opposite sides of an iron ring or ‘torus’ to induce current. Faraday’s law is a single equation describing two different phenomena: the motional EMF generated by a magnetic force on a moving wire, and the transformer EMF generated by an electric force due to a changing magnetic field.
6|Page EXPERIMENTAL ANALYSIS: OBJECTIVE
To determine the Faraday’s law of electromagnetic induction using a
copper wire wound over an iron rod and a strong magnet.
APPARATUS REQUIRED -:
Insulated Copper wire An iron rod
A strong magnet A draw board for base/platform
A light emitting Diode (LED)
THEORY
The magnetic flux (B) through a surface is the component of the
magnetic field passing through the surface. The SI unit of magnetic flux is weber (Wb), and the COGS unit is , Maxwell.
7|Page Magnetic flux is usually measured with a flux meter, which contains measuring coils and electronics that evaluate the change of voltage in the measuring coils to calculate the magnetic flux. If the magnetic field is constant, the magnetic flux passing through a surface of vector area S is
Where is the magnitude of magnetic field having the unit of
Wb/m2(T). is the area of the surface and is the angle between magnetic field lines and the normal. For a varying magnetic field, we first consider the magnetic flux through a small amount of area where we may consider the magnetic field to be constant.
From the magnetic vector potential and the fundamental theorem of
the curl, the magnetic field may be defined as
where the line integral is taken over the boundary of the
surface, which is denoted as
LAW
The most widespread version of Faraday’s law of electromagnetic
induction states that
“The induced electromotive force in any closed surface is equal to
the negative of the rate of change of magnetic flux through the circuit.”
This version of Faraday’s law strictly holds true only when the closed circuit is a loop of infinitely thin wire, and is invalid in other circumstances as discussed below. 8|Page A different version, the Maxwell-Faraday equation is valid in all circumstances.
The magnetic flux changes due to the change in magnetic field.
Faraday’s law of electromagnetic induction states that the wire loop acquires an EMF, defined as the energy available per unit charge that travels once around the wire loop.
Equivalently, it is the voltage that would be measured by cutting the
wire to create an open circuit. And attaching a voltmeter to the leads. According to Lorentz force law,
And the EMF of the wire loop is
The Maxwell-Faraday equation states that a time varying magnetic
field is always accompanied by spatially varying, non- conservative electric field and vice versa.
The Maxwell-Faraday equation is
9|Page 10 | P a g e CONCLUSION
Faraday’s law of electromagnetic induction, first observed and published
by Michael Faraday in the mid nineteenth century, describes a very important electromagnetic concept.
Although its mathematical representations are cryptic, the essence of
Faraday’s law is not hard to grasp. It relates an induced electric potential or voltage to a dynamic magnetic field.
This concept has many far reaching ramifications that touch our lives in many ways: from shining of the sun to electricity and power in our homes.
We can all appreciate the profound impact Faraday’s law has on us.
